Marko Perković (pronounced [mâːrkɔ perkoʋit͡ɕ]; born 27 October 1966) is a Croatian musician who has been the lead singer of the band Thompson since 1991.

During his career, Perković has attracted controversy in the media over his performances and songs, some of which are alleged to glorify or promote the World War II-era Croatian fascist Ustaše dictatorship.

Perković joined the Croatian forces and used the American Thompson gun during his time in the war, which became his nickname and later, his stage name.

[6] Perković during his career has cited Mate Bulić, Nightwish, Iron Maiden, AC/DC and Dream Theater as main influences.

[12] Perković created controversy by allegedly performing "Jasenovac i Gradiška Stara", a song that openly glorifies the Ustaše regime, its crimes against humanity during World War II in the Jasenovac concentration camp and Stara Gradiska concentration camp, in which the genocide of Serbs took place.

[13] The Simon Wiesenthal Centre filed complaints to Croatia's state television channel regarding its broadcast of a singer accused of expressing nostalgia for the Ustaše, although Perković denied any connection with that time period.

[16] In 2015, Perkovic performed in Knin in front of some 80,000 spectators for the 20th anniversary celebration of the Croatian military’s Operation Storm with many of those in attendance singing pro-Ustasha songs and chanting slogans such as "Kill a Serb" and "Here we go Ustasha".

[16] Perković and his band's inclusion in Croatia's celebration of the national team's second place finish in the 2018 FIFA World Cup also garnered controversy and criticism.

[17] Perković's alleged glorification for the Ustaše have led to him being accused in some publications, including the Simon Wiesenthal Center, of being a "fascist singer".
